, lighting devices intended for therapeutical adjustments ,of the casing b use. The main objects of the invention are to obtain certain desired vertical and angular light and rigid structure; an to make such structure foldable into compact relation with the casing so that the device may be conveniently carried or shipped.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Figure 1 is a perspective view of a casing and supporting structure therefor constructed according to this invention.

Fig. 2 is a perspective view showing the supporting structure in folded relation with .respect to the casing.

Figs. 3 and 4 aredetails of the tween the yoke and standard.

Devices of the general class to which this invention relates may be employed as electrijoint becal heaters for general use, as well as for therapeutical purposes. In the latter use of the device, the heat and light maybe regulated to the desired degree of mildness by cutting out ofvcircuit a number of the resistance lamps which are usually mounted in the casing and provide the necessary heat and light. The eflect of'the heat and light on the patient may be further regulated by an angular adjustment of the casing or by moving it toward or awa from the patient. These adjustments also acilitate the use of the device for local applications when the patient is in sitting or lying position.

The legs of the supporting structure in the present device may rest on each side of a be or cot so thattheca sing is directly over the patient. The casing. may then be adjusted vertically or around-"its pivot.

The structure shown comprises a pair of standards or legs '1 of triangular form as shown in Fig. 1. The upper ends of the.

standards fit within recesses 2 in the lower ends of an inverted U-shaped member or means of a yoke 3 which serves to rigidly connect the swung outwardly beyond a position slightly past a vertical position whereby they will securely support the casing when set up.

The upper end of the yoke is formed to provide an aperture or guideway 6 in which is slidably mounted the shank 7 of a handle 8. The shank 7 is pivoted at its lower end by the flush headed pin 9 to a short arm 10 rigid with the casing 5. This arm 10 is of the same cross section as the shank 7 and -may accordingly pass through the aperture 6 in the yoke 3, as shown in Fig. 2. A flatheaded thumb screw 11 is threaded into the yoke 3 in position to clamp the shank 7 or the arm 10 to the yoke. With this arrangewith the handle and serves as a fastening means for the chain 12.

In the operation of the device, the vertical adjustment of the casing 5 is eflected by pulling the handle 8 upwardly and locking it in set position by means of the screw 11. Angular adjustment is effected by pulling the chain 12 through the aperture 14, and passing a link of the chain over the pin 15.

When the device is not in use or is to be transported, the supporting structure is folded against the casing as shown in Fig. 2. This is efiected by first drawing the handle upwardly until the arm 10 of the casing extends through the aperture 6 in the yoke. The casing may be clamped in this position by means of the screw 11 and then the legs or standards 1 are folded inwardly and the handle 8 is swung downwardly against the casing. p In order to be able to lock the legs 1 positively either in their extended or folded positions each leg 1 is provided with a spring Angular adjustment of the casing 'ment, the casing 5 may be secured-in its difactuated detent 16, which has a. shank exin the cheek 0 pieces of the socket member 2. The slot in one side of the socket member is enlarged at its ends to provide recesses 18 in which the enlarged head of the detent 16 may be locked by the detent under the action of the spring 20.

When it is desired to treat a larger area of the patients body than is covered by the casing of the small sized device herein shown, or when the apparatus is to be used to perform the functions of a heat and light bath cabinet, two of these devices may be placed end to end and a blanket thrown over them and supported by their standards.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In a device of the class described, the combination with a casing for heating or lighting elements of a supporting structure therefor comprising a pair of standards connected by a yoke at their upper ends, and a shank slidably mounted in said yoke, said shank being pivoted, at its lower end to said casing. e

2. In a device of the class described, the combination with a casing for heating or lighting elements of a supporting structure therefor comprising a pair of standards connected by a yoke at their upper ends, a shank slidably mounted in said yoke, said shank being pivoted at its lower end to said casing, and means for clamping said shank to said yoke.

e 3. In a device of therlass described, the combination with a casing for heating or lighting elements of a supporting structure therefor comprising a pair of standards connected by a yoke at their upper ends, and

nae oee a shank slidably mounted in said yoke, said shank being pivoted at its lower end to said casing, said standards being pivotally connected to the yoke whereby they may be folded inwardly underneath the casing.

5. In a device of the'class described, the

combination with a casing for heating or lighting elements, of a support arched over said casing, an arm rigidly secured to said casing, a shank pivotally connected to said arm, and a guideway in said yoke for receiving said shank and through which the shank and said arm are slidable.

6. In a device of the class described, the combination with a casing for heating or lighting elements, of a support arched over said casing, an arm rigidly secured to said casing, a shank pivotally connected to said arm, a guideway in said yoke for receiving said shank and through Which the shank and said arm are slidable, and means for adjusting said casing to diiferent angular positions relative to said shank.

7. In a device of the class described, the combination with a casing for heating or lighting elements, of a support arched over said casing, an arm rigidly secured to said casing, a shank pivotally connected to said arm, a guideway in said yoke for receiving said shank and through which the shank and said arm are slidable, a chain secured to said casing at one side of said shank, guiding means on said shank for said chain, and means for securing said chain to said shank for adjusting the angular position of said casing.
